Hello everyone!
Today we are going to see about JavaScript datatypes
JavaScript is a dynamically-typed language, which means you don't need to declare the data type of a variable before using it. however, understanding the different data types in JavaScript is crucial for writing effective and efficient code.

The 8 data types of JavaScript

  1. Number: Represent numeric values, such as integers or floating-point numbers.
  2. String: Represents text such as words or sentences.
  3. Boolean: Represents true or false values.
  4. Null: Represents the absence of any object value.
  5. Undefined: Represents an uninitialized or non-existent variable
  6. Object: Represent complex data structures, such as objects or arrays.
  7. Symbol: Represents a unique symbol value.
  8. Bright: Represents a large integer.

Examples and Use Cases

  • Number: let age = 25;
  • String: let name = "john";
  • Booleans: let is admin = true;
  • objects: let person = {name: "john", age:25};

Conclusion
Understanding JavaScript data types is essential for writing robust and maintainble code.by knowing the different data types and their uses,you can avoid common pitfalls and write more efficent code.
